钢与硬质合金高频钎焊研究现状
Current research status on high-frequency brazing of steel and cemented carbide
摘要
Abstract
In the field of industrial metal cutting,saw blades undertake the task of cutting various hard materials.Their structure comprises a substrate and cutting tips,joined together through brazing.The substrate is typically made of steel,while the teeth are fabricated from cemented carbide.Due to the low toughness of cemented carbide,it is often brazed to structural steel for use.High-frequency brazing,based on the principle of electromagnetic induction,offers advantages such as rapid heating and a minimal heat-affected zone among numerous brazing methods,making it the optimal choice for saw blade welding.This paper focuses on saw blades used industrially for metal cutting,delving into the application of high-frequency brazing for joining dissimilar materials-specifically steel and cemented carbide.Centring on the characteristics of brazing filler metals and welding parameters,it analyses their impact on weld quality through the lens of filler metal wettability,alloy element reactions at interfaces,joint microstructure,and joint strength and mechanical properties.关键词
